For convenience of description, the wound mass, whether of conical or cylindrical form, is hereinafter referred to as a "package; the material being wound into the package, whatever its nature, is designated yarn; and the support or carrier for the package called a tube." It is to be understood that these terms are to be interpreted severally in their generic sense as indicating any type of package, all kinds of strand material and any preferred shape of core or carrier on which the material is wound.

In the present drawings the invention is shown as applied to use with a standard type of winding machine known and sold under the trademark Universal. It is' to be understood, however, that the present device or attachment may be applied to use with other types of winding machines within the scope and purview of the present invention.

Referring to Fig. 1, the basic winding machine comprises a main frame 2 of box-like construction provided with opposite bearings 3 at the top which serve as the journals for a horizontal shaft 4, usually termed the winding-spindle. Arranged below and parallel with the windingspindle 4 is a cam-shaft 5 journalled in bearings 6 at the opposite sides of the frame 2. The spindle 4 constitutes the drive-shaft of the machine, being driven from a belt-pulley 8 adapted to be clutched to the shaft by means of a member 9 fast thereon. The clutch-member 9 carries a belt-pulley In which is connected by a belt H to a similar pulley l2 located therebelow. The pulley I2 is fast with and drives a shaft [3 journaled in a bearing M in a gear-casing l5 at the side of the main frame 2. At its inner end the shaft [3 carries a pinion l6 meshing with a gear [1 fast on the end of the cam-shaft 5.

The cam-shaft 5 carries a cam 2|! fast therewith and constructed with a cylindrical rim formed with a helical groove 2| in its periphery.

The groove 2i is engaged by a roller or follower 22 on a slide or crosshead 23 which constitutes the means for reciprocating the thread-guide 25, to be later described. The crosshead 23 is slidable in a grooved guideway in a traverse-frame 26 constituted by a horizontal member 21 supported from legs 28 pivoted on bushings 29 which serve as the journals for the cam-shaft 5.

Connected at one end to the crosshead 23 is a traverse-rod 30 which slides in a suitable groove in the traverse-frame 26, see Fig. 2, with its outer end connected to impart reciprocatory motion to the thread-guide 25. Fastened to an outward extension 3| of the horizontal member 2'! of the traverse-frame 26 is a plate or traverseframe back 32 which is constituted to direct the course of the thread-guide 25 during its reciprocation. The construction and arrangement of the parts of the machine as thus far described are in accordance with the standard type of winding machine previously referred to. The only alteration necessary to the machine to adapt the present device or taper-end attachment for codperation therewith is a slight change in the form of the guide-plate or traverse-frame back 32 which is fastened to the overhanging part 3| of the frame 26 by means of screws 33. As indicated in Figs. 1 and 2 the substitute traverse-frame back 32 is provided with a pad having a finished face 34 for the attachment of a sickle-shaped bracket 35 to be later described.

In machines of the present type the threadguide 25 is usually constituted as a disk or button, so-called, provided with a notch 31 through which the yarn or other strand feeds to the winding. The thread-guide button 25 is fitted to an opening at the top of a bifurcated arm which is arranged to slide along the rearward face of the traverse-frame back 32. In some cases the traverse-frame back may be arranged with its bearing face 38 parallel with the axis of the winding-spindle, when the machine is fitted for winding packages of cylindrical form; while in other instances, the guiding face 38 may be inclined at an angle to the axis of the spindle when it is desired to wind conical packages. As herein illustrated the machine is shown adapted for winding packages of generally conical shape and for this purpose a tapered mandrel is provided on the overhanging extension of the spindle 4 for carrying and rotating a conical paper cop-tube indicated at C in the drawings.

The arm 40 carrying the thread-guide 25 is ordinarly attached directly to the outer end of the traverse-rod 30, but in the present form of construction a different mounting is provided for the thread-guide whereby to adapt it to rock on an axis crossing its line of travel. Referring particularly to Fig. 2, an elbow-shaped arm or mounting 42 is connected to the traverse-bar 30 at 43 with its right-angled portion extending downwardly and terminating in a fork or bifurcated portion 44. The sides of the fork 44 straddle a fixed guide-rail 45 constructed in the form of a relatively narrow bar of rectangular crosssection carried on the bracket 35, previously referred to.

The bracket 35 has a portion 46 fastened to the finished face 34 of the traverse-frame back 32 by means of screws 41, see Figs. 1 and 2. The depending sickle-shaped extension of the bracket 35 is of ribbed construction or T-shape in crosssection, reaching down beneath the overhanging portion of the traverse-frame 26 and then curving upwardly at the rear in an arm 36. Projecting across the top of the lower curved portion of the bracket 35 is an arm 48 to which the horizontal guide-rail 45 is fastened by screws 49.

The threadguide arm which mounts the thread-guide 25 is of articulated construction comprising a main upright portion 40 hingedly joined to a lower elbow-shaped element 50. The element 50, in turn, is swiveled to the member 42, previously described as being connected to reciprocate with the traverse-bar 30, see Figs. 3, 4, 5 and 6. The element 50 is pivoted on a headed and shouldered stud 52 riveted through the depending portion of the member42. The guidearm 40 is hinged to the element 50 by means of a pivot-pin 53 held in curled over ears 54 on the member 50. As shown most clearly in Fig. 5, the lower portion of the arm 40 is curled around to form a bearing 55 for receiving the pivot-pin 53 extending between the ears 54 on the element 50. A relatively thin, fiat spring 56is riveted to the upper part of the arm 40 at 51 to adapt its lower end to bear against the end of a finger 58 bent back from the opening between the cars 54 on the member 50. The spring 51 tends to maintain the arm 40 bearing against the finished face 38 on the traverse-frame back 32.

The thread-guide supporting element 50 is formed with an arm 59 extending laterally to the right as viewed in Figs. 4 and 5 and carrying a bowl or-roller 68 journaled on a pin 6| secured in its outer end. The bowl or roller 60 is adapted to travel in'the slot or guideway 64 of a track or guiding member 65 to cause the thread-guide to rock on the transverse pivot-stud 52 carried by the reciprocating member 42.

The track 65 is pivoted to a boss or hub 66 on the extremity of the rearward upstanding arm 36 of the bracket 35. A stud 61 screwed into a boss 68 on the back of the track 65 has its enlarged body portion journaled in the hub 66 on the bracket 35 whereby the track is mounted to rock in a substantially vertical plane. It will be observed by reference to Fig. 5 of the drawings that as the thread-guide mounting 42 is reciprocated with the traverse-bar 38 the element 50 to which the thread-guide arm 40 is hinged will be caused to rock about the pivot 52 as the roll 60 on its arm 59 rides up and down the incline of the track 65. The track 65 is located in horizontal position at the start of the winding as illustrated in Fig. 4 of the drawings whereby to cause the thread-guide to be reciprocated without any rocking or oscillating motion of the member 50 on the stud 52. It is noted, however, that the hinged connection of the arm 48 with the member 50 permits a rocking motion of the arm on the pivot 53 to adapt the thread-guide 25 to follow the taper of the cone-tube C. As the winding progresses, the track 65 is rocked or canted in the manner indicated in Fig. 5 to cause the guide-arm 40 to be rocked about the axis of the pivot-stud 52 to swing the guide 25 inwardly at each end of the traverse. In this way the traverse of the guide is progressively shortened to dispose the yarn in layers of gradually decreasing extent which effects the shaping of the package with a tapered or conical end or ends in the manner as later more fully explained.

The track or guide member 65 is swung or rocked to incline it to the normal path of reciprocation of the thread-guide 25 by and through the movement of the guide outwardly away from the axis of the winding-spindle. As the threadguide 25 recedes from the winding-spindle the traverse-frame 26 is swung back on its pivot bearings 29 concurrently with the increase in diameter of the winding. Conveniently, the means for rocking the track 66 may be operated from the movement of the traverse-frame 26. Such means may be of different forms, two embodiments thereof being shown in the present drawings.

Asshown most clearly in Figs. 2, 3, and 6 of the'drawings, the guide member or track 65 is formed at one end with a rearwardly extending arm 69 carrying a spherically-headed stud 19 adapted to slide in an inclined guideway or groove II formed in a cam member 12 supported from the main frame 2 of the machine. The cam member 12 is adjustably mounted on an arm or bracket 13 fixedly attached to the side of the frame 2. The upper end of the arm 13 is secured to the frame 2 by means of a stud I4 which serves a further purpose inpivotally mounting the traverse-frame dog sector 15 constituting a part of the standard machine. The stud 14 has a flange 16 against which the upper end of the arm I3 is bound by a nut 11 screwed onto the end of the reduced portion of the stud. The lower.

end of the bracket 13 is secured to the frame 2 by means of a bolt 18 which also serves as the holding means for a member 19 constituting a stop acting to limit the swinging movement of the traverse-frame 26. Preferably, the bracket 13 is formed at the ends with slots for the stud l4 and bolt 18 to provide for its vertical adjustment in initially setting the cam member 12 at the proper height.

The cam member 12 is of U-shape or bifurcated form as viewed from the rear, see Fig. 5, with one of its legs provided with a hub 89 through which projects a stud 8| screwed into the arm 18. A nut 82 on the outer threaded end of the stud 8| secures the cam member 12 in place while adapting it to be adjusted angularly about the stud M to regulate the inclination of the cam-groove II. A finger or pointer 83 on the upper end of the cam member 12 has a mark adapted to register with numbered graduations on an arcuate plate 84 forming part of the arm 13. The angular position of the cam member 12 may be altered to cause it to eflect a greater or less extent of inclination of the track 65 in accordance with the amount of oscillating motion to be imparted to the thread-guide to obtain the desired formation of the package; that is with a greater or lesser degree of taper at its end or ends.

Fig. 'I of the drawings illustrates a modified form of construction of the means for canting or tilting the guide member or track 65. In this latter form of construction a bell-crank lever 85 is pivoted on a stud or pin 86 carried by the lower weighted arm 81 of the traverse-frame 26. One arm 88 of the bell-crank 85 is connected by a link 99 to an ear 9| on the underside of the track 65; the link being conveniently formed of wire with its end bent at right-angles and inserted through a hole in the ear 9|. A cotter-pin 92 and washer 93 at the end of the angular part of the link 99 hold the latter in place and the lower end of the link is also bent at right-angles and inserted through a hole in a stud 95 swiveled to the end of the arm 86 of the bell-crank 85 with nuts 96 for securing it in place.

The opposite arm 98 of the bell-crank 85 is slotted at 99 to receive a stud I99 at the end of a link I9l whichis attached at its opposite end to.

a stud I92 fast in some rigid part of the machine, for example, the bracket I94 which supports the tension-device I96, see Fig. 1 of the drawings. It is to be noted that the link IN is pivotally connected to the arm 96 of the bellcrank 85 by the stud I99 and, likewise, the opposite end of the link IN is pivoted on the fixed stud I 92 to provide freedom of movement between these parts as the traverse frame 26 swings on its pivot 5. The connection of the link I9l with the arm 98 may be adjusted by loosening the nut I99 and sliding the stud I99 in the slot 99, whereby to regulate the extent of motion communicated to the bell-crank lever 85 under the movement of the traverse-frame 26 during the growth in the package; it being noted that as the thread-guide 25 swings away from the axis of the windingspindle the movement of the traverse-frame will rock the bell-crank lever 95 to cause the link 99 to tilt the rearward end of the track 65 downwardly. The method of operation of the complete machine with the attachment constructed as first described is as next explained.

Referring to Figs. 1 and 2 of the drawings, this latter view shows the cam 12 adjusted to the furthest extreme of its angularity to effect a maximum shortening of the layers of yarn during the winding of the package, it being noted that the index pointer 83 is set at the last graduation mark 4". At the start of the winding the transverse-frame 26 is adjusted to the position shown in Fig. 2 with the thread-guide 25 resting against the surface of the cop-tube C on which the winding is to be performed; the tube having been placed on the winding-mandrel and secured thereto by suitable means as usually provided. With the traverse-frame 26 in this position the spherical-headed stud I9 is positioned adjacent the upper end of the groove 1| in the cam 12, whereof the guiding track 65 will assume a horizontal position as illustrated in Fig. 4 of the drawings.

The yarn or other material is supplied from a suitable source, not herein shown but usually placed below, the strand 3 being led up through the tension-device I95, passed through the notch 31 in the thread-guide 25 and its end secured to the cop-tube C. The machine is started to operate by rocking the starting lever H9, shown in Fig. 1, and as the winding-spin'dle 4 is rotated the yarn will be wound onto the cop-tube C while being traversed back and forth longitudinally thereof by the guide 25 which is reciprocated from the cam 29.

As the winding proceeds the increase in diameter of the package causes the thread-guide 25 to recede from the axis of the winding-spindle with the traverse-frame 26 swinging on its bearings 29. During the continuous reciprocation of the traverse-bar 39, actuated from the cam 29, the member 42 slides along the rail 45 and the thread-guide mounting comprising the arm 49 and pivoted member 59 are reciprocated therewith with the roller 69 sliding in the groove or guideway 64 of the track 65. With the track 65 in horizontal position at the start of the winding the roll 69 travels in a course parallel with the path of the traverse-rod 39 and consequently no oscillating movement will be imparted to the guide mounting or member 59 carrying the arm 49. Therefore, the thread-guide 25 will be traversed to its maximum extent as determined by the throw of the cam 29; or throughout substantially the whole length of the cone-tube C or other support on which the winding is performed.

However, as the yarn is built up on the coptube C and the guide 25 recedes from the axis thereof the swinging movement of the traverseframe 26 will cause the spherical-headed stud 10 on the arm 69 of the track 65 to slide down the inclination of the groove H in the cam I2. Under this action the track 65 is rocked or canted away from the horizontal as indicated in Fig. 5 of the drawings to an extent commensurate with the growth in the winding. The track 65 is thus gradually rocked on its pivot 61 so that as the thread-guide carrying member 50 is reciprocated the inclination of the track will cause the roller 60 to continuously rock/the member 50 on its pivot 52. Under this action the thread-guide arm 40 is rocked inwardly away from its extremes of traverse at each end of the throw with a progressively increasing extent of motion, thereby causing a gradual shortening of the layers of winding throughout the building of the package. This progressive shortening of the traverse of the thread-guide results in building the package with gradually shortened courses to form it with tapered or conical ends as indicated in Fig. 5 of the drawings.

In the embodiment of the invention as illustrated in Fig. 7, the operation of the machine is substantially the same, that is as regards the tilting or canting of the track 65 during the reciprocation of the thread-guide 25 to effect a progressive shortening of its traverse. In this case, however, the displacement of the track 65 is effected by the action of the bell-crank lever 85 which is rocked by and with the movement of the traverse-frame 26. As the traverse-frame 26 rocks on its pivot its lower weighted arm 81 swings to the left, as viewed in Fig. 7, carrying the bell-crank 85 bodily with it. As the bellcrank 85 is moved in this manner the link llll connected thereto causes it to be rocked in a contraclockwise direction to draw the link 90 downwardly to tilt the track 65 in the same manner as previously explained in connection with the first described construction.

Fig. 6 illustrates an alternative arrangement of the track 65 which may be adopted when it is desired to increase the length of the package to be wound. With the track initially set with its rearward or inner end canted upwardly the thread-guide arm will be rocked outwardly at each end of its traverse and thereby the extent of traverse of the guide 25 will be increased over the normal throw of the cam 20.

In some instances it may be desired to wind 9. package with only one of its ends tapered and for this purpose the present device or attachment may be organized as shown in Figs. 8 and 9 of the present drawings. In this embodiment of the invention the thread-guide and its connections are of the same form and arrangement as previously described but the traverse-control track H5 is mounted in a different manner. In place of the bracket 35, previously described as the mounting for the track 65, the present form of track I I5 is swiveled on an arm or bracket I 16 supported at the ends of two elbow-shaped arms ll! held in bosses H8 on the traverse-frame back 32. The bracket I I6 has a pair of arms H9 for supporting a cylindrical rod I20 which takes the place of the rail shown in Fig. 2, the reciprocating member 42 having its lower end shaped to straddle the sides of the rod to slide thereon. At one end of the bracket H6 is an upstanding finger or projection l2l formed with abearing hub I22, through which projects a shouldered stud I23 screwed into a boss on the back of the track H5. With this arrangement the pivot for the track I I5 is located at the outer end thereof while its inner end is connected to the link 90 shown in Fig. '7 of the drawings as connected to the bell-crank lever 85. It will thus be apparent that the rocking movement of the bell-crank lever will cause the track H5 to be tilted downwardly at its inner end during the growth in the winding while its outer end remains fixed.

It is to be further noted that the pivot for the track I I5 is located at a point corresponding with the outer extreme of movement of the roller 60 on the arm 59 of the reciprocating member which mounts the thread-guide arm 40. Consequently, as the track I I5 is canted downwardly at its inner end it acts on the thread-guide to shorten its stroke only at the rearward end of the traverse, that is, as it moves toward the frame of the machine. When the thread-guide 25 moves toward the outer end of its traverse the roller will ride up the incline of its track to restore the guide to upright position as indicated by the dash lines in Fig. 9, this terminal point of the traverse remaining constant throughout the whole winding. In other words, as the package increases in diameter the traverse of the threadguide 25 will be shortened at one end only as the roller 60 rides down the incline of the track H5 to rock the arm 40 in the manner indicated in Fig. 9. The package produced by this method of winding is sometimes wound on a wooden tube or holder with a head or flange abutting the flat end of the yarn mass. This character of spool or package is unwound by drawing the yarn oiT over its tapered end, thus avoiding any tendency of the strand to snarl or entangle and maintaining a. more uniform tensionof delivery.

It will be observed from the foregoing that the present invention provides a particularly simple yet eflicient mechanism which may be employed as an attachment for winding machines to control the formation of the packages wound thereon. The device may be arranged to wind a package with practically any degree of taper at its opposite ends or may be constituted to form the package with one end flat and the other tapered, all within the purview of the invention.
